摘　　要：振弦式传感器是水利工程和结构监测中应用较为广泛的设备之一。针对振弦式传感器输出信号微弱、放大检测中容易受到干扰而造成的测量精度下降问题,通过一个大坝高边坡安全监测工程应用实例的研究,从硬件的合理设计和软件的数据处理两方面详细分析和有效解决了振弦式传感器测量过程中的干扰问题,大大提高了振弦式传感器的测量精度。Vibrating wire sensors are the most widely used equipment in hydraulic engineering and structure monitoring. To the question that the measurement accuracy decline is caused by the weak output signals from vibrating wire sensors and is susceptible to interference during amplification and detection, some methods are proposed to analyze and solve the interference effectively both from the reasonable hardware design and data processing on software design through a survey of studying on a practical project of a high slope of dam safety monitoring engineering, which has greatly improved the measurement accuracy of vibrating wire sensors.
